    • PROBLEM TO BE SOLVED: To provide a double anchor which is constructed at a low cost so as to drive two resistance plates individually into the ground and open them at predetermined underground depths and connect them to each other. SOLUTION: The open side of a two-leaf type resistance plate unit D is made to face downward and the shaft 21 of a base plate unit C is inserted into the through-gap 24b of a through-rib 24 to place the two-leaf type resistance plate D on a base plate 20. Further, a driving pipe 28 which has a longitudinal cut groove 28' so as not to obstruct the retaining ring 22 of the shaft 21 is put onto the shaft 21 from the top of the shaft 21 and the rear end of the driving pipe 28 and the rear end of the shaft 21 are made to agree with each other. In this state, the two-leaf type resistance plate D is driven into the ground. In this process, the retaining ring 22 of the shaft 21 is put onto the guide plate 31 of a resistance plate unit E which is driven into the ground beforehand and, when the retaining ring hits the receiving plate 33 of the resistance plate unit E and its movement is blocked, the driving pipe 28 only is driven to open the two-leaf resistance plate unit D along both the warped sides (warped upper tab 20a) of the base plate 20 of the base plate unit C.

    • PROBLEM TO BE SOLVED: To provide a self standing device enabling the free execution of the fixing and reinforcing means for a base stationed on the bottom surface of a dug hole to a ground according to the peripheral situation of the ground, and an executing method therefor. SOLUTION: This self standing device for a planted tree consists of a base formed by connecting inside ends of each of the base members 3 with the side surfaces thereof in the vicinity of the inside ends each other in a state of facing the opening along the longitudinal direction of the base members 3 consisting of plural C shaped steel, base fixing means fixed with each of the base members 3 for inserting into the ground 20, supporting poles 9 fixed to a supporting base freely transferable along the hollowness of the base members 3 so as to be installed for standing through an opening of the base members 3, binding rings 15 surrounding the outer periphery of the supporting poles 9 as ring shapes and binding both pieces with a bolt, and a deformed plates having multiple holes 16 connected to a wire 18 surrounding the root of a plant and fit to the upper edge of the outer periphery of a root pot 21. At the outside surface of the lower end of the deformed plates having multiple holes, hooking plates 19 inserted to the supporting poles 9 and also hooked to the bottom ends of the binding rings 15 are installed and fixed.
